A 9-year-old child's mother visits the dental clinic reporting oral ulcers, fever, and peeling skin on the palms and soles. She also mentions the child has a history of premature tooth loss and excessive sweating. Additionally, the child has been using a newly marketed teething gel for the past month. What is the most likely diagnosis?

Explanation

The symptoms of oral ulceration, fever, peeling skin on palms and soles, premature tooth loss, and increased sweating, combined with recent use of a new teething gel, strongly suggest Acrodynia. This condition, also known as mercury poisoning, commonly presents with these features in children. Other listed conditions do not typically present with this combination of symptoms.
